Architects and Engineers Specifications The loudspeaker system shall be a 2 watt ported loudspeaker system that includes one Acoustimass module and two or four satellite speakers. It shall be capable of producing 93 db SPL average in a 45, ft3 room with an RT6 of 1 second in a range of 5 Hz to 16 khz (±3 db). The module shall have one 5.25" (133 mm) dual voice coil low frequency driver. The module shall have an input impedance of 6 ohms (5 ohms for surface-mount module) for direct connection to un-equalized low impedance amplifier sources. The system shall be configured for use with either a 7/1 V input or a low impedance input. The transformer shall offer multiple taps of 25 W, 5 W, 1 W, and 2 W. Each satellite speaker shall have one 2.5" (64 mm) full-range driver. The nominal average dispersion shall be 17 at 6 db. The input connectors shall consist of multi-position screw-type barriers on the flush-mount Acoustimass module, a spring-type barrier connector for the 7/1 V inputs and a screw-type barrier strip for direct 4-8 ohm input on the surface-mount Acoustimass module, a two position guillotine connector on the flush-mount satellite, and a two position screw-type barrier on the surfacemount satellite. Wire jumpers for transformer settings shall be provided. Removable covers shall shield all bass module input and jumper connections. The flush-mount Acoustimass module shall have dimensions of 15.4" (391 mm) outer flange diameter; 14.25" (361 mm) ceiling hole diameter; and 7.5" (19 mm) height to top of housing. It shall weigh 14 lb (6.36 kg). The surface-mount Acoustimass module shall have dimensions of 14." H x 8.7" W (w/bracket) x 13.6" D (356 mm x 221 mm x 345 mm) and shall weigh 17.5 lb (7.9 kg) with attached mounting bracket. Each flush-mount satellite speaker shall measure 6.2" (157 mm) outer flange diameter; 5." (127 mm) ceiling hole diameter; and 5." (127 mm) to top of housing. It shall weigh 1.9 lb (.9 kg). Each surface-mount satellite speaker shall measure 3." H x 3." W x 4." D (77 mm x 77 mm x 12 mm) and shall weigh 1.75 lb (.8 kg). The flush-mount Acoustimass module and flush-mount satellite enclosures shall be composed of PC/ABS with an expanded metal grille and shall meet plenum ratings when used with a plenum cover. The surface-mount Acoustimass enclosure shall be composed of high-density wood composite with solid color PVC laminate, black or white. The surface-mount satellite shall have a cloth grille and black or white polymer finish. The loudspeaker shall be the Bose FreeSpace 3 loudspeaker system. Safety and Regulatory Compliance The Bose FreeSpace 3 system loudspeakers have passed extensive testing and comply with the following specifications and uses: UL148 listed: General-Purpose Use, UL Category UEAY, File Number S 5591 Air-handling spaces (ceiling plenums), FS3 flush-mount module and flush-mount satellite: UL3 When used with the PCFS3F and PC-FS3B Plenum Cover accessories NFPA-7 National Electric Code 22, Article 3-22(c) NFPA-9-A-1996 Installation of Air Conditioning and Ventilation Systems, Section 2-3.1.1(a), Exception 3 EMC Directive 89/336/EEC and Article 1 (1) of the directive, EN581-1, and EN582-1, as signified by the CE mark.
